Follow two basic rules:

1. OnInit is intended FOR INITIALIZATION !!! CopyBuffer cannot be used inside OnInit !!!
2. Be sure to read the ArraySetAsSeries help

to set your zzBuffer with ArraySetAsSeries as true might help.  that's the key difference vs mql4's.

Print("zigzag Handle = ",MaHandle,"  error = ",GetLastError());
ArraySetAsSeries(zzBuffer,true);
int copy=CopyBuffer(MaHandle,0,0,limit,zzBuffer);
